The SCHLAGE COMMERCIAL L583214 is a mounting post designed for the L Series door hardware line, used with doors measuring 2.25 inches in thickness. This small but critical component provides the structural connection point needed to properly install L Series lever or trim assemblies. At 2.5 inches in length and 0.23 inches in both width and height, it is a compact, precision-fit part. Locksmiths, commercial door hardware installers, and facility maintenance technicians working with Schlage L Series mortise locks will find this post a necessary replacement or installation component.
This mounting post is intended for commercial and institutional door hardware applications where the L Series lock system is specified. It is sold as a single unit and suits doors with a standard 2.25-inch door thickness requirement. Typical installation scenarios include new commercial door hardware builds and field replacements where the original post has been damaged or lost during service.
Designed as an OEM-style replacement mounting post for use with Schlage L Series mortise lock door hardware assemblies on 2.25-inch doors.
Installation should be performed by a licensed locksmith or qualified commercial door hardware technician. Before servicing or replacing any lock component, ensure the door is secured in an open position and that all related hardware is disassembled per standard locksmith practice. Refer to the Schlage L Series installation documentation to confirm correct post orientation and seating before reassembling trim components.
